RESX file extension - Microsoft Visual Studio .NET XML resource template

What is resx file? How to open resx files?

The resx file extension is associated with Microsoft Visual Studio.

The resx files are used for developed application resource files or resource template files.

The RESX resource file format consists of XML entries, which specify objects and strings inside XML tags. One advantage of a RESX file is that when opened with a text editor (such as Notepad or Microsoft Word) it can be written to, parsed, and manipulated. When viewing a RESX file, you can actually see the binary form of an embedded object (a picture for example) when this binary information is a part of the resource manifest. Apart from this binary information, a RESX file is completely readable and maintainable.

The resx file contains a standard set of header information, which describes the format of the resource entries and specifies the versioning information for the XML used to parse the data.

The following example shows what a typical set of header statements in a resx file might look like.

<?xml version="1.0" encoding="utf-8"?>
<root>
<xsd:schema id="root" xmlns="" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">
<xsd:element name="data">
            <xsd:complexType>
                <xsd:sequence>
                    <xsd:element name="value" 
type="xsd:string" minOccurs="0" msdata:Ordinal="2" />
                </xsd:sequence>
                    <xsd:attribute name="name" 
type="xsd:string" />
                    <xsd:attribute name="type" 
type="xsd:string" />
                    <xsd:attribute name="mimetype" 
type="xsd:string" />
            </xsd:complexType>
        </xsd:element>

Following the header information, each entry is described as a name/value pair, very similar to the way in which strings are specified in a txt file. A name/value pair in the .resx format is wrapped in XML code, which describes string or object values. When a string is added to a .resx file, the name of the string is embedded in a <data> tag, and the value is enclosed in a <value> tag, as in the following example.

<data name="string1">
   <value>hello</value>
</data>

When an object is inserted into a .resx file, the same <data> and <value> tags are used to describe the entry, but the <data> tag includes either a type or MIME type specifier. The type specifier holds the data type of the object being saved. The MIME type specifier holds the base type (Base64) of the binary information stored, if the object consists of binary data.

How to convert file with extension RESX:

As far as we know, this .resx file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
